Signs you need leak investigation and inspection

What usually causes it?

Hidden water paths

Water can travel along bars, decks and linings before it shows.

Not the lantern

Sometimes the source is the flat roof, a parapet, a gutter or a wall above.

Roof lanterns in Greater Manchester

Damp, mild winters keep moss and algae growing on flat roofs and lantern frames, which holds water against seals and blocks weep slots. Regular clearing makes a real difference in wetter areas.

Urban grime and traffic film dull glass and frames quickly; a clean and seal check makes a tired lantern look and perform much better.

What should you expect to pay for leak investigation and inspection in Greater Manchester?

Guide price, per visit£145–£295 ex VAT£174–£354 inc VAT

Most leak investigation and inspection jobs come in between £145 and £295 ex VAT (£174–£354 including VAT), per visit. Towers or scaffold, where needed, are priced into the quote. Your fixed price is confirmed in writing before any work starts.

Do you need permission in England?

In England, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building Regulations 2010, so we set out the route in writing first. Listed buildings need listed building consent from the local council for alterations, and conservation areas can have extra controls; like-for-like repairs are treated differently from changes, so check with the council's conservation officer first.
